Hi
You have to do a "leak down test" with the Xwedge to find compression. A normal compression test does not work here as explained by Calum.
When interested I can send you the article about it which I made. PM me.
For Xwedge parts Zodiac.nl is a good source and Phil has a lot of stuff too.


One ant does not know anything, 2000 are a super-intelligent brain. That's like this helpful forum.
